I’m playing streams…iis there any callback which executes at the time parameter.
eg. song lengthms is 300000.
callback must write “hello world” when song come to 270000 ms.
Should be useable with mp3 and ogg files.
Yes I know that I can do that via timer…..

I’m not aware of a callback that can be set on a timer, but one way to do it
without using a manually programmed timer would be to call FSOUND_Stream_AddSynchPoint
– you would have to work out how many samples 270000 ms equates to
(using sample rate & bit depth)

Then you can set a sync callback by calling FSOUND_Stream_SetSynchCallback
which will be called at the sync point you set
